WATCH-BRACELET.

Yorkyand whose post-office address'is.3 33 Central Parkwestpin saidcity,have 1nvented certain new and useful Improve-- lowing is aspecification.

ments in Watch-Bracelets, of which the fol-' This invention relates to adetachable link for the end of a bracelet and means for securing thelink to the watch case. Generally the wearer of a watch bracelet desiresto use thewatch for other purposes, such as achatelaine, brooch watcl1,etc., and as'a bracelet watch isgeneralIy-prOVided with a small link orother means of attachment on its edge, when" such a watch is worn-asabove mentioned, it is readily apparent that a bracelet watch is beingused... Thus, convertible watchesof this type are not much in use.

The object, thereforefof this invention 1s toprovide a watch case withmeans *to 7 which same; Fig. 9? is a plan view, partly in seccarried outby my invention, a more'particu- I'L'CtIOII of the arrows; Fig. 7 is aplan view which my improved end link maybesecured and detached at will,the means on f the watch case not being discernible, so that the wearercan use the watch for other purposes than for a bracelet watch, withoutit being known that a bracelet watch is being used. These and otherimprovements are lar description of which appears below.

Throughout the various views -of the drawings, similar referencecharacters-designa'te slmilar parts.

It is obvious that" my mproved detachable end' link and means forsecuring the. same to thewatch case may be used in connection"with anyform of agbracelet, al-' though in this-instance I have shown a soofaseries of outer links 1, and inner links 2 withretracting springscontained between the inner and outer links. T hewatc'h 3 has a link 4to which one'end ofthe bracelet chain is'attach'ech'a special form ofdetachable link 5 being used,=if desired.

The back 6 of the watch is hinged to the center 7- by a hingef'S whichis mounted on the pintle 9 which extendsthrou'ghthe cen- The detachablee'nd'link consists of two resilient side members 11, connected fat'oneendby the crOsspiece IQ, which is engaged by the inner link of. theadjoining link; gThef opposite ends of the side members 111 are off-setas at 13 and on'the ends'of said off-set portions are formed inwardlyextending studs 1a which extend intothefrecesses 10 the same; andFig. i2is perspective view. :of thesame.

in the watchfcase hingef A sliding collar 1 5 is mounted on the linkanddraws theside members 11 together and holds the 'studs'14:

in the recesses 1 0.' Depressions 16 are formed in the side members 11adjacent the oflfset portions 13 to hold the, collar.15"inplace andprevent the same from inadvertently slipping'back and allowing the. linkto free itself fromthe watch. A blockl'lis secured to'the'inner side ofoneof'the, side members to limit. the movement ofthe side- 1memberstoward one another when the collar .1577 moved forward intopos1t1on'ad-]acent the I ofF-setportions '13, and the stu'dsliareposition in the recesses 10;

From thellfor'egolhgi e operation of the I detachable linkwill bereadily understood; I

To removethe link fromthe'watch, thecol- .lar'15fis slid awavfromtheoif-set portions 13,which" allows the armsill to-spring away from oneanother, the studs 14 moving out of'the recesses 10"so that the link canbe readily removed.

In the embodiment of my inventio'n'shown in Figs. 7, Sand .9, I haveshown a'link member having two trough-shaped side members 18 connectedat the ends by'cross pieces 19 and intermediate the ends by a crosspiece 20. Slidably mounted in said link is the catch member 21 havingresilient tongues 22 and 23. The tongue 23 is slit as at 24,

dividing it into two portions 25, the ends of 1 said portionsbeing'ofi-set as at 26 and at? the ends of said offset portions areformed the studs 14 which are adapted to enter the 1recesse'slO.inlhewateh case-hinge. In order to hold the two parts 25togetherso-that the tstuds remain inplace in the ree'esses 10, a-slidingecellar 27 is mounted on thetongue 23. A recess 28 is formed inthe tongue '22 Y which engages thecross-pieee .ZOtoholdthe catch; member21 within the link member when the catch member isthus placed.
